I have a TI 84 Plus Silver Edition. It got wet at the beach. I tried drying it with a hair dryer, but it still won't turn on. What can I do?

There is no such thing as a TI89 Plus Silver Edition.

If you mean the TI-89 or TI-89 Titanium, press diamond / (the diamond key below the 2ND key, then the divide key).

If you mean the TI-83 Plus Silver Edition or the TI-84 Plus Silver Edition, press MATH left-arrow 4 .

Enter the numerator and denominator then press Math ToFrac

If you hve questions please let me know. Thanks for using Fixya.

TI calculators have an annoying habit of dimming the screen when the batteries are changed so that it appears as if the calculator isn't turning on. Turn the calculator on (or at least press the ON key). Press and release the 2ND key. Press and hold the Up-arrow key for a few seconds and see whether the screen becomes legible.

If that doesn't work, add a comment to this post and we'll go from there.

I would suggest putting it in some dry rice. That will soak up all the moisture. You might also try drying it with a hair dryer.

That actually is a result of water damage. You probably need to replace it, or see about getting it taken apart and dried if the water damage was recent. DO NOT take it apart yourself. Go somewhere and ask if that is possible.

press 2nd and then the down arrow over and over until the contrast is adjusted. Did you read the manual?
